linx-ING DEvIcE.

Application led May 2S, 1924, Sera1-rNo.' 716,446.

T all whom t may concern lie it known that l, JOHN liris'rmga Vciti-y y zenv of the United States, residing'at-Portland, in the county of Multnomah and State of Gregoii, have invented certain new ant useful Improvements in aQMining Device, ofl which the following is aspeciication.

y This inif'ention relates to an: improved fuelY ,mixing device especiallyV designedY for use in connectionV with internal combustionuenf gines, although the device may well bel employed in various other situations, andseeks, among. other.V objects, topprovide a device which (will function to effectuallyanix `the o fuel gas andair of the fuelsupply of'an engine or the like so thaty thoroughly effi cient combustion will behad.

The invention seeks, as a further object, to provide a device which may be interposed between the engine carbureter and theA in take manifold of the engine for mixing'the fuel in its passage from thecarbureter tothe engine so that the ultimate carbureted `product will not only readily lignite but will burn o completely,

crease in power but also effecting a reduction in the formation of carbon in the engine cylinders'.

Gther and hereinafter.

In the drawings: y Figure 1 is a view partly in elevation and partly in section, showing my improved device interposed between a conventional carbureter and engine intake manifold,

incidentalrobjects will appear ister with' the confronting flanges 11 of a' carbureter 12 and engine intake manifold 13, providing agasket between the flanges. The carbureter and manifold are, of course, `conventionally illustrated and through the flanges 11 and through the plate 10 are the usual bolts 14l securing the parts together. Formed in the plate 10 centrally thereof' is an opening 15 in which is disposed a spider 16a-nd pressed through the Y yand the flanges 20. thereby not only effecting an in- Y Figure 2 is a detail sectional view through' f inserted hub ofthe spider to vextend axially of said opening. 4is a shaft 17 frictionall'y. locked against rotation.y portions' ofthe shaft at opposite sides of the plate l10 is a pair of mixingfans. These flans include fan discs 18 which maybe struck from. suitable sheetv metal and are provided with a plurality of (radial. blades,

discs being identical withfthe exceptionthat the blades of the discs are, as .shown in. Figure 1, twisted infopposite directions.-

liountfing the,v discs are hubs` 19 which are journaled upon theshaft17-and are provided at corresponding ends thereof -with annular flanges 20; to confront the Vhubs of the spider when i fit Yoverthe hubs 19 abutting the flanges' 20 and surrounding the hubs to seat against said discs are clamping rings 21. After the discs and clamping rings have been applied, the

hubs are then formed atk their outer ends' with flanges 22 to bear against the rings21 for clamping the discs between said rings- Thus, the discs and hubs will be secured to turn in unison. Fitting over'the endsof the shaft 17 are retaining parts in assembledr'elation. Y

` 'As will now be seen in view of the foregoingdescription, when the engine is running and fuel vapors are drawn from thecarbureter 12 into the manifold 13,the fans of the device will be caused to rotatel upon the shaft 17 and since the fan blades vare oppositely twisted7 the fans will turn'in opposite directions. throughv the fuel vapors to mix and comf mingle the component parts of the fuel charge with' the result thata homogeneous fuel supply will be delivered to the engine. MoreY completel combustion than is now obtained will thus berealized, with a correspondingy increase in the efficiency of the engine as `well as a corresponding decrease in the formation of carbon in the engine cylinders. As will be observed, the fans are quite closely spaced so that any liquid particles thrown froml the blades of either fan toward the other will strike the blades of the latter fan.

when the impact will, of course, serve to break up the particles to be takeny up by the raporous' currents flowing through the fans. Furthermore, the fan nearestthe carbureter will, as will be seen, tend'to impart a swirl- Mounted upon the yend.

cs 18 are apertured centrally to soV , washers 23 for the fans and inserted through v y the shaftfare pins 24 removably securing the Thus, the fans will cut ing motion to the fuel vapors but the swirling currents thus started Will be opposed by the movement of the fan furthest removed from the carbureter. rI `hus, the latter fan will cut through the currents set up by the former fan in a direction opposite to the flow of said currents, with the result that the fan furthest removed from the carbureter will exert a rubbing action on the currents impacted thereagainst for removing practically all unvaporized particles from the fuel mixture. I accordingly provide a particuvlarly effective device for the purpose set forth and, as will be seen, a device which may be readily installed.

in Figure 4 of the drauf'ings, I have illustrated my improved device Iin connection with a conventional boiler 25. Leading to an approved liquid fuel burner Within the boiler is a pipe 26 to which is connected a supply pipe 27 and interposed between said pipes is the present device, indicated as a Whole at 28, bolts 29 being employed for connecting the pipes as well as securing the device in position. Thus, as the liquid fuel is forced under air pressure from the pipe raconte Z7 to the burner Within the boiler, the fuel will be broken up into particles by the fans of the device so that better combustion will take place.

Having thus described the invention, what I claim is:

A mixing device includinga lcody plate having an opening and provided With a spider to extend across said opening, a shaft eX- tending through the spider axially of the opening, hubs journaledy upon the shaft at opposite sides of the spider and provided vith flanges to confront the spider, fan discs fitting over the hubs to abut said flanges and provided with oppositely twisted blades, and rings surrounding the hubs to confront the discs, the hubs bei-ng formed at their outer ends with flanges bearing against said rings for clamping the discs between the rings and said first mentioned anges whereby the hubs and discs will be secured to turn in unison forming oppositely rotating fans at opposite sides of said body plate.

In testimony whereof I afx my signature.
